Variations for rental and dividend income

How easy is it to obtain a variation to include dividends and rental income in the CM calculation?

At a guess I think it would be very tricky to make such a variation stick.

If you have been trading less than a year you could simply tell your accountant not to issue a dividend until you file the tax return. Alternatively, close down the company and start a new one with someone else as sole director (who would get the dividend) with you remaining the sole employee. Or, keep the company as it is and increase the number of people entitled to receive a dividend (thus reducing your own payment).
